Application filed May 13,

T0 all whom t may concern:

Be it known that I, WAYNE S. EvaNs, a citizen of the United States,residing in the city and county of Philadelphia, State ot Pennsylvania,have invented a new and u seful Umbrella Rib and Stretcher, of which thefollowing is a specification.

My invention consists of an improvement in umbrella constructionembodying a stretcher of channelled or U-shape, the vchannel being ofreversed form at an end thereof whereby while one portion is adapted tobe pivotally mounted in a channelled rib another portion is adapted toreceive the ad jacent portion latter and so folding the rib andstretcher in compact form as to occupy together small space and also topreventfl-.torsion and twisting of the rib and stretcher.

The invention is satisfactorily illustra-ted in the accompanyingdrawing, but-the im-y portant instrumentalities thereof may be varied,and so it is to be understood that lthe inventionis not limited to thespecific details shown and described, as long as they are within thespirit or scope of the claims.

Figure 2 represents a longitudinal section thereof.

stretcher in folded condition.

of a portion of a stretcher removed from Figure 11.

Figure 13 represents a perspective view of the bearing member for thepivot of the joint of the rib and stretcher shown in Figures 9 and 11.

Figure 1e represents an elevation of an other embodiment of theinvention.

Figure 15 represents a perspective view of a stretcher showing anotherembodiment of the invention.

Similar numerals of reference indicate corresponding Aparte in thegures. Re ferring to the drawings,

1 designates the rib of an umbrella, and El designates a stretcher whichis connected therewith in a manner hereinafter described, both stretcherand rib being of channelled or U shape.

In 'the channel of the rib at the place of junction of the stretcherwith said rib there is fitted the pin 3 which is irmly secured to therib by swedgingor pressing the material. of the rib tightly against theside of the pin as at 4, said pin having therein at one end an openingto receive the axial pivot 5 which is passed through an opening in theear 6 on the adjacent terminal of the stretcher, the ends of said pivotbeing headed on the eiiierior of said ear so that said ends are`inclosed by the sides of the channeled or' U-shape rib and so removedfrom the exterior of the sides of the rib.

The crown pf the stretcher near the pivotal end is swedged as at 7whereby the reim tive wallsmof lthe channel of 'the stretcher arereversed so that portions of 'the channel project in oppositedirections. The portion at the end is reduced or iiattened and enteredinto the adjacent portion of the channelled rib with which it isconnected by the Pivot .f3 while the major portion of the stretcher isadapted to receive the corresponding portion of the rib and to embracethe latter. By this provision'the stretcher and rib fold compactlytogether in the closed condition of the umbrella, thus reducing their-thicirness as thus folded and preventing lateral disconnection of thesaine and relieving with separated ears 6 to receive said ivot,Vv

said ears 6 being on opposite sides o said ear 8, the heads of saidpivot being on the exterior of said ears 6, and so inclosed Withinl-andby the side of the channel of the rib, said pin in this clase beingsolid, but to which I do not limit myself.

In Figures 9, 10 and 11 the pin is tubula and so has a plurality of ears11, While the stretcher has its ears 10 contacting and mounted Withinsaid ears 11 on the pivot 5 so that the ears Il are on the exterior ofthe ears 10,'y said pivot having its heads on the exterior of the earslland as in the previous case inclosed` Within and by the side channel ofthe rib.

In Figure 14, the stretcher has at its pivotal end a plurality of ears6. In Figure l5, .ll show a stretcher provided with inverted channelsone at each ends being pivotally connected with the rib and the otherend being pivotally connected with a runner of the umbrella.

Having thus described my invention what end thereof, one of the r Iclaim as new and desire to secure by Letters Patent, is

l. A channelled stretcher in umbrella construction having a reversedchannel at an end thereof.

2. In an umbrella construction, a channelled stretcher having at an endthereof a reversed channel and a channelled rib, the. main channelledportion of the stretcher being of a size to receivesaid rib and embracethe Walls thereof.

3. In an umbrella construction, a 'channelled stretcher having itschannel at an end portion thereof projecting in reversed directions, anda channelled rib the pivotal end of said stretcher being mounted in saidrib, and

the main channel portion of the stretcher being of a size to receivesaid rib and embrace the walls thereof.
